Breast Cancer

Among all cancers in females, he takes the initial place. In most cases, breast cancers develops inside presence of precancerous changes. This is primarily a benign mammary dysplasia and papilloma ducts.

Breast cancer is represented macroscopically nodular and diffuse forms, along with cancer of the nipple along with the nipple from the field (Paget's disease in the breast). For the nodular cancers are characterized by the node using a diameter as high as several centimeters. In certain instances, a strong knot, is permeated with whitish layers tissue penetrating to the surrounding fatty tissue, on other occasions - a soft, juicy around the cut, splits easily. Diffuse prostate type of cancer is covered to get a considerable distance, the contours of the tumor are marked bad. Sometimes the cancer invades your skin and forms on the surface of decaying mushroom formation - a cancerous ulcer. In some cases, the tumor spreads down the surface with the breast and all the iron is roofed having a dense shell.

In histological structure are the following forms of cancer of the breast:

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive breast cancers may be intralobular (lobular carcinoma in situ), and intraduct (ductal carcinoma in situ).

Infiltrating (invasive) cancer is characterized by varying examples of tissue and cell irregularities, which permitted to distinguish different amount of malignancy. This type of cancer include, especially, infiltrating ductal and lobular carcinoma, which will has got the structure of scirrhus, and also Paget's disease.

Causes of Breast Cancer.

The causes of cancer of the breast often are hormonal changes inside body: the entry into menopause, when there is a dynamic restructuring in the hormonal regulation with the woman, the ovaries lose their activity, decreased output of progesterone and estrogen, your body will go through, "hormonal crisis." The mammary gland and endometrium (lining of the uterus) are most attentive to these changes, the breast type tissue starts to dissolve and become replaced by fat.

Scientifically established that this female hormones estrogen-, plays a vital role inside growth and development of breast cancers. The excess hormones inside body results in a favorable background for developing the sickness. The least active hormones estrogen behave when pregnant and after birth - during breastfeeding. It is proved that the birth and prolonged breastfeeding (greater than twelve months) to lessen the potential risk of developing breast cancers. On the other hand, abortion lead to hormonal "explosion" in the woman's body that could trigger the continuing development of tumors. So far there is no consensus concerning the impact about the progression of tumors of hormonal contraceptive drugs, however it is belief that these drugs reduce the risk of developing breast cancers, but increase the chance of developing cancer in the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast can cause harmful environmental factors: the environment, in addition to inflammatory diseases previously deferred breast - mastitis.

In addition, patients which has a category of first-degree relatives with breast cancer (mothers and sisters) chance of developing a tumor increasing by greater than half - familial varieties of cancer.

Benign breast diseases for example fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone usually do not lead to cancer, but concurrently, create an unfavorable background because of its development.

The source of breast cancers may be the effects of radiation, like irradiation with the chest for other diseases (lung tumors, the lymphatic system), prolonged and frequent chest X-ray studies on inflammatory diseases or pulmonary tuberculosis.

Constitutional obesity can lead to cancer of the breast and female the reproductive system, with an excess dimply skin inside body, it is an outside endocrine organ and actually starts to actively produce hormones-estrogens, whose action and provokes the growth and development of tumors.

Symptoms of Breast Cancer

There are several forms from the growth of breast cancer:

- Nodular form, the commonest, is characterized by a dense knot of 0.5 to 5 cm or even more, it is characterized by all in the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without any clear boundaries, "spreading" with the breast and skin. For the first couple of forms are characteristic signs of inflammation: pain in the breast, a bright beautiful red colors with the skin it raises body's temperature to 39 degrees C. In view of these symptoms often occur, and errors in carried out patients treated for inflammatory diseases, that happen to be named and they are described these forms breast cancers. When tubular carcinoma breast cancers cover as being a "skin" of the contracting and decreasing in size.

In certain instances, cancer of the breast manifests within the form of metastases inside lymph nodes on the affected side, often does not detect the tumor itself - show hidden breast cancer.

For small tumors of the breast, any symptoms arise. The most observant ladies and their husbands can detect tumor site within the gland by accident, but in the large breast to detect small size hard knot. Revealed a knot can be painful when pressed, round, smooth and agile, this speaks in support of a benign tumor. Signs of malignancy other: a good knot to touch the stone, its surface is uneven, it is stationary or slightly shifted, may be firmly fixed on the surrounding tissue or skin, usually painless, can reach a substantial size (over three to five cm and infrequently 10-15 cm).

Need to evaluate the surface with the skin over the tumor: the malignant process will be observed retraction with the skin, buying in the folds, wrinkles, a symptom of "lemon peel" - a nearby swelling of the skin in the tumor, may be a direct tumor invasion to the skin surface, then it will become a bright beautiful red colors and sprawl as "cauliflower."
